The result shows that the viscosity is greatly increased while the solid coal powder distributed in the inside of slag and result in poor separation of molten iron and slag.

研究结果表明，未燃煤粉以固体质点形式分散在初渣内部时，使初渣粘度大大增加，渣铁熔体难以滴落；

Results show that an increase of ions with 4-coordination number in molten slag makes the bulk viscosity increasing, while that with 6-coordination number is contrary.

结果表明随着熔渣中四配位离子的增加，其体相粘度增加，而六配位离子的作用则相反。
